SEWIN G-MACHINE.

Specification of Letters Patent.

rate-.atea July so, 191s.

application filed October 6, 1917. Serial No. 195,104.

This invention relates to certain improve-,

ments i'n sewing machines and has relation more particularly to a sewing machine employed 1n,the production or repair ot shoes,

and. it is an object of the invention to provide a novel and improved device or`produciiig a channel or groove iii the sole of a shoe wherein the stitches are received.

It is also an object of the invention to provide a novel and improved device or attachment for cutting channels in a shoe sole or the like which may be removed and applied w'itlpconvenicnce and 'aeility.

The invention consists in the details of construction and in thccombination and arrangement of the several parts ofi'n y improved sewing niachineA wherein certain limportant advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be, hereinafter more fully set forth.

The novel-features otl my invention will hereinafter be definitely claimed.

In order that my invention maybe the better understood l will now proceed to describe' the saine with reference to the accompany ing drawings wherein:

Figure l is a view in elevationl eta work support having an attachment constructed in accordance with an embodiment of my invention applied thereto, the adjacent portion ot' the sewing machine being diagrammatically indicated by dotted lines;

Fi". 2 is a view in' to )lan of a work support having my improved attachment;

Fig. 3 is a sectional view taken substantially on the line--B of Fig. 2;

Fig. 4 is a sectional view taken substantially on the line Lt-4 of Fig. 2;

Fig. 5 is a view in side elevation ot' the Cutting attachment as herein embodied unapplied; and

Fig. 6 is a view in side elevation ol a turtlier embodiment. ot' my improved attachment. l

As disclosed in the accompanying draws Aopen at the side of the plate P ings S denotes a work support adapted to be mounted in applied position upon the trame ot' the sewing machine and in properposition relative tio the needle ot the sewing ma chine mechanism. f

',lfhe forward or outer endportion of the support S at'. substantially its transverse center 'is provided with a recess 1 in which eX- tendstlie'bloeli L) depending from the outer end portion of the plateI l). The plate P `is disposed longitudinally ot' the support S and is arrai'iged at substantially the transverse center thereof. It -is also preferred that' the side wall of the block 2 and the adjacent portion of the side walls ot' the platel l) be inwardly vand downwardly beveled indicated at The plate l and the block depending therefrom extend beyond the outer end ot' the support S and have pro-` upper portion of said slot 4iat oneend-.js as indicated at 5, to atl'ord a recess.

Snugly litting within the recess 5 -iswfanr arm' t) having one end portion provided with" the depciidingplug 7. lug Y is 'beveled as indicated at 8 to irmly contactwith the adjacent beveled face 3 of the head i), below the recess' whereby f arm t-is held against rocking or tilting n'i'ovement. It will also be self-evidentl that the lug 'l' coact-s with a beveled'face of the head 2 to hold the arm (3 againstendwise movementI to et'ectually 'brace' the same;

against the strain imposed thereupon during".

the working operation and whichy strain is' considerable 1n view ot the tact that the cutl ting member 9, to be hereinafter more particularly referred to, actsl directlyupon the sole. The opposite end of the arm 6, when applied within the recess 5 terminates sub stantially .'[iush with the adjacent end of the needle slot -t and said inner end portion of the arin G is provided with the upstanding cutting member 5) preferably formed integral therewith and which member serves to properly out al thread receiving channel inl the sole o't a shoe as'the worli is passed over the outer' end of the plate during a sewing operation. Il`he outer end of the pla-te? is provided with a threaded opening 10. in conm'iunication ,with the reee 5 and through which opening` l0 'is disposed a binding screw 11. The inner end of the screw 11 seats within a recess 12 produced 80A i rlhe inner tace of the when it is desired to cut .7 is beveled as indicated at in the adjacent face of the arm 6. Bythis arrangement. it will be at once self evident that the arm G is effective-ly locked in applied position yet be readily removed when desired. l

The operation of my 'improved attachment is believed to be clearly apparent to those skilled in the art to rvhich my invention relates and although it may be Well 'to state that a particular advantage of my present invention is the provision of means whereby the arm 6 may be readily applied a channel Within the sole of a slice or whereby said attacliment may be removed. When a rubber or composition sole is being applied to a shoe it is not necessary that a groove or channel be' cut therein, therefore when a rubber or composition solo is' being used the attachmentv as particularly illustrated in Fig. 5 is removed and in lieutheieoiI applied the attachment particularly illustrated inFig. 6. This attachment comprises am arm 6 adapted to snugly lity Within the recess 5 and has one end portion provided with the depending lug 7. The inner Jface of the lug S3 to irniy contactwith the adjacent beveled i'ace 3 of the head 2 below the recess 5 whereby the arin' is held against rocking orftilting movement. The opposite end oi the arm d when applied within the recess 5 terminates substantially flush with the adjacent end of the needle slot el in the same -manncr as has been hereinbetore set forth relative to the arm G. The upper i'acc of the arm G is iiat and unobstructed so that no cutting action orother effect is'had upon a rubberof coinposition sole. A face of the arm 6 is provided ywith a recess 12 with which is adapte, ed to co-act the screw ll as has hereinbefore been set forth relative to the arm 6.

An especial advantage of my present invention is the fact that 'the attachinentl as articolari' illustrated in Fim 5 `be r moved and the attachi'nent as particularl i lustrated in Fign 6 may be applied Within substantially enana-lf a minute or vice versa Whereas in the shoe serving machines now narcose which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without materially departing from the principles and spirit thereof and for this reason li do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein 'shown in 'carrying out my invention in practice ex;

cept asV hereinafter claimed.

I claim: In a sewing machine, a Work support provided With a needle slot, said qmember being; provided with an open groove in its outer face in communication` with the end portion of the slot in advance of the portion of the slot through which the needle ofthe sewing machine passes, said groov being in longitudinal alinement with said slot, an arm snugly itting Within the groove and having its inner end substantially flush .with the adjacent end of the needle slot, the inner end portion of the arm being provided with an opstanding cutting member, the opposite end portion of the-arm being provided With a lug disposed in a direction o posite to the cutting member, the opposed aces of the lug and the working support being Correspondingly beveled .and in contact one with the other, the bevel of the Work support being disposed downwardly and in wardly so that the lugof the arm underlies the support, and a clamping member threaded through -the Work support and en` gagging the side face of the arm,`

In testimony whereof l hereuntfraiiix my signature in the presence of two Witnesses.
